What's so surprising? Clearly there's a limit on the growth of auto infrastructure.
I like to think that bikes offer a path out of the rat race being that transportation is 2nd in cost of living expenses.
(however, a 60+ cyclist I know bikes 15 miles on grueling hills to his low end job, disputes this dream??)
And so does the tech world where there are still massive profits to be made on sustaining the auto culture (gps, hybrids, ev's,google navigation, etc.) (And I don't necessarily think that's bad)
